I picked up a nice 12 ga B2000 made in 1974. It has an IC choke tube but no markings as to who made it. I've not seen one quite like it before. If anyone could help me identify the manufacturer, I'd really appreciate it. The threads on the tube are 2 1/8 inches long, with 4 slots for a Browning wrench. Anyone have any thoughts? Thanks!
I can assure, they are not Browning. Definitely an after market tube, and a thin-wall at that. Looks like a Briley, though it may be an early edition with those long threads.
I never seen anything like it. Looks like an awefully long thread section. Maybe Briley could shed some light on the question?
Mystery solved! Hannah at Briley did confirm it is their choke tube - 25ML. They can still be made by special order. Thanks for the input!
